Abstract

The modernization of a software system is a complex and expensive task and requires a deep understanding of the existing system. The capability of re-factoring a complex application into some high-level views is mandatory to elicit its structure and start localize possible changes. The high number of different implementation technologies imposes a model-based, neutral approach to reconstruct the structure and hide unnecessary details. OMG supports this view and proposes KDM (Knowledge Discovery Meta model) as means to describe software systems in detail, but unfortunately KDM supports a component-oriented decomposition of the system of interest only partially. To bypass this limitation, the paper proposes the COMO (Component-Oriented MOdernization) meta model to extend KDM, by borrowing recurring concepts from component-based solutions and software architectures, and to support a proper componentization of the system we want to modernize. The paper presents the main elements of the COMO meta model and exemplifies them on a simple case study.

面向组件的软件应用现代化元模型

软件系统的现代化是一项复杂而昂贵的任务，需要对现有系统有深入的了解。将一个复杂的应用程序重构为一些高级视图的能力是必需的，以引出其结构并开始本地化可能的更改。大量不同的实现技术要求采用基于模型的中立方法来重建结构并隐藏不必要的细节。OMG支持这种观点，并提出了KDM(知识发现元模型)作为详细描述软件系统的方法，但不幸的是，KDM只部分地支持对感兴趣的系统进行面向组件的分解。为了绕过这个限制，本文提出了COMO(面向组件的现代化)元模型，通过从基于组件的解决方案和软件体系结构中借用重复出现的概念来扩展KDM，并支持我们想要现代化的系统的适当组件化。本文介绍了COMO元模型的主要元素，并通过一个简单的案例加以说明。
